Based on some advice from another forum, I got a stronger acid (stronger than white vinegar) muriatic acid (aka hydrochloric acid) to test the rocks.

6 of the 13 pieces of rock tested positive. So it ended up being the rocks.

At least I know now. It's a real bummer.

Here is one picture that shows how pretty the rocks looked:
